Notes:
1. Sensing resistance in air R
0
is measured under controlled ambient conditions, i.e. synthetic air at 23
±5°C and 50 ± 10% RH for RED sensor and synthetic air at 23 ±5°C and ≤ 5% RH for OX sensor.
Sampling test.
2. Sensitivity factor is defined as Rs in air divided by Rs at 60 ppm CO. Test conditions are 23 ± 5°C and
50 ± 10% RH. Indicative values only. Sampling test.
3. Sensitivity factor is defined as Rs at 0.25 ppm NO
2
, divided by Rs in air. Test conditions are 23 ± 5°C
and ≤ 5% RH . Indicative values only. Sampling test.
4. Sensitivity factor is defined as Rs in air divided by Rs at 1 ppm of NH
3
. Test conditions are 23 ± 5°C
and 50 ± 10% RH. Indicative values only. Sampling test.
